Explosion-proof firefighting equipment for underground coal mines relies on high-expansion foam to rapidly suffocate and cool down large-area solid/oil fires, making it a core piece of equipment for mine fire rescue.
Connected to an external underground fire-fighting water source, and mixed with high-expansion foam concentrate, a foam mixture is formed via a proportioning mixer.
The mixture is evenly sprayed onto a foaming mesh; an explosion-proof axial flow fan blows air at high speed, amplifying the liquid into 500-800 times its original volume of foam.
The large amount of foam rapidly rushes towards the fire area, isolating air, absorbing heat, covering combustibles, and suffocating the fire.
The entire electrical system is designed with mine-grade explosion-proof and explosion-proof structures, allowing safe use in hazardous underground environments containing gas and coal dust, with no risk of spark ignition.
